 I think your question is not very well formulated ! Because the standard edit control accept those characters...
What are you looking for exactly ? Maybe you want to implement a kind of parser or xomething like that ? If yes, look in the articles of this website, there is a section about parsers (don't remember exactly where). Otherwise, try to be a little bit more explicit.

actually, i think it's far from being perfect...
i really liked to add formal calculation into it (like "x + x" returning "2x")
i also like to add more personalization, like allowing the users to configure the number of digits they'd like to appearing as a result, etc...
I also thought (one day i was dreaming too much) to adding a graphical area to draw functions (2D or 3D why not )
but i saddly don't have enough time to make all these at the moment...
hey, you know what ? i really liked to share this with you (if you agree of course)... it would be grateful to me if you accepted to become my co-author on that article, or at least, help me with some useful tips/suggestions...
i'm waiting for your answer "hurrily"
sincerly,

Hi everyone,
I am currently finishing my vocational training. After this 3-year-phase I will be transferred to another department, which uses a different approach:
In my current department, most GUI-design is done with WinForms or VB6. The "new" department uses the MFC for most of its GUI-stuff, so I need to get into that ASAP.
That means I am pretty much relying on you guys to provide me with some pointers to sources where I can read up on GUIs with the MFC and the MFC in general.
Thanks in advance.
Cheers,
Sebastian

Why does ReadFile function hang after successfully reading a byte from port?
|
|
|
|
|
You must give more detail about the problem if you want help.
The opinions expressed in this communication do not necessarily represent those of the author (especially if you find them impolite, discourteous or inflammatory).

I wrote a program in Visual C++ to implement Serial Communication. The program compiles successfully and runs also. After initialising the ports, when a byte is written to the port, on one computer and is read on another computer (which is connected to the earlier computer) the code works. But when I try to read the port again the program simply hangs. The only way out is then to stop the debugger.
I used the initialisation code provided in a article posted on this site itself (the one written by Eshwar). But to implement read and write I only used the functions ReadFile and WriteFile respectively.
|

|
|

If there is no data coming on the port anymore and if the read timeout of the port is set to infinite, the ReadFile function will wait until data is received (thus it seems to 'hang').
To change this behavior, you can use the SetCommTimeout function.
But I suggest you to read a little more documentation about how serial ports work because you seem to lack some important informations there...
Hope this helps

Respected Sir,
I read your suggestion and tried setting the timeout to a lower value. I set it to the following values :-
commTimeout.ReadIntervalTimeout = 10;
commTimeout.ReadTotalTimeoutConstant = 10;
commTimeout.ReadTotalTimeoutMultiplier = 1;
commTimeout.WriteTotalTimeoutConstant = 10;
commTimeout.WriteTotalTimeoutMultiplier = 1;
Still no use. The ReadFile function makes the program hang. Please can you suggest some sample values.
Thanking you.

Still not enough information. It is well known that ReadFile and WriteFile both work. The problem must be in your code. Post some sample code.
It may be simply that you call ReadFile again when there is nothing for it to read; what if you send it another byte from the other computer?
The opinions expressed in this communication do not necessarily represent those of the author (especially if you find them impolite, discourteous or inflammatory).

In non-overlapping mode, when you call ReadFile, it will wait until it reads a byte at least. It also depends on the input size as I remember.
You really should not call ReadFile or WriteFile in your main thread, you better use another thread to do this, which will keep your program responding, and it is better to use proper time-out values for the port, so that ReadFile will fail after a certain amout of time if nothing is read.
Does that do any help?
this is this.
